 J. D. K ; C. B, Clarke, 



Rootstock very long and stout, inclined. Leaves 2-18 in., linear- or obovate-ob- 

 Icng in outline, 1-2J in. diam. across the broadest part; leaflets usually close and 

 often imbricate, ^-1^ in,, tip rounded, sessile, many-nerved, the alternate nerves 

 smaller, upper decurrent; petiole slender or stout; lower stipules membranous, upper 

 leafy toothed. Flowering stems •with one or two leaves and a few-flowered irregular 

 corymb. Flowers J in. diam. ; pedicel elongating after flowering. Calyx silky, 

 lobes triangular acute ; bracteoles various, usually toothed. Petals orbicular, yellow. 

 Stamens 20-30. Achenes few, ^ in. diam., four times as large as in any other Indian 

 species, dark brown ; receptacle low, villous, 



Var. ohscura ; covered with soft spreading hairs, not silvery, leaflets \ in. broadly 

 oblong membranous less closely serrate softly hairy on both surfaces. — Kumaon at 

 Kalari, alt. 13,000 ft., StracK ^ Wintcrb, I hare but one specimen, and though 

 I find no approach to pubescence on it, judging from the variation of F, splendens, 

 Mooniana, and Leschenaultiana, it may well be referable to peduncularisj with which 

 it altogether agrees in habit, flower, and achenes. 



Var. Clarkei ; dwarf, sparsely silky, not silvery, leaflets narrowly oblong. — Sikkiffl 

 at Yakla, alt, 14,000 ft., C. B. Clarke.

20. P. leuconota, Bon Prodr. 230 ; leaflets numerous (alternate some- 

 times minute) oblong obtuse sharply closely serrate clothed beneath with ap- 

 pressed shining silky hairs, flowering stems exceeding the leaves, flowers small 

 subumbellate, Dracteoles entire, achenes few hairy or glabrous, style very short 

 ventral. Wall. Cat. 1021 (excL spec, of peduncularis) : Lehm. Revis. Potentill 66,

Alpine Himalaya; Garwhal, 10,000 ft., Madden \ Nipal, Wallich ; Sikkim, alt. 

 10-16,000 ft., J. D, H.—BisTRiB. Borneo (Kina Balou, alt. 11,000 ft., Low). 



Rootstock very stout, sometimes 1 in. diam., inclined. Leaves 2-6 in., very numer- 

 ous, linear in outline or rather broader upwards; leaflets close or sparse, J-J in., ses- ; 

 sile, glabrous or hairy above ; petiole with appressed hairs. Flowering stem ^^^^^ . 

 ascending, with usually a leaf about the middle, and an imperfect whorl of reduced: 

 ones at the inflorescence. Flowers J in. diam., crowded the pedicels elongating stif- 

 fening and forming an imperfect umbel as the fruit advances. Calyx silky, lohes 

 acute; bracteoles linear-lanceolate, entire. Petals obovate, retuse or rounded at the

 toothed to the middle or deeper, scape exceeding the lea^ es 1- rarely 2-flowerea, 

 petals much exceeding the calyx, achenes many minute quite smooth, styles yery 

 short ventral. Wall Cat. 1010. 



Alnine Himalaya, from Garwhax. alt. 10-14.700 ft to Sivktm. alt. 15-18,000 ft. 



Very variable in habit and stature, forming at high elevations dense hard moss- 

 like tufts, strewed with golden flowers and with the leaves so small and crowded 3S 

 with difRculty to be distinguibhed ; at lower elevations the leaves are 4-6 by 4 '"• 

 Leaflets oY^^^H\Xt and alternate, uniform, Jj^_^ in. broad, crowded and overlapping ^ 

 scattered, flat, or complicate ; petiole slender; stipules very large, membranous, ob-
